In 1909 Ernest Rutherford shot tiny particles at a sheet of gold foil. He expected all of the particles to move straight through the gold's atoms. Instead some of the particles moved through but other?

Why did Rutherford conclude that an atoms nucleus has a posotive charge instead of a negative charge?
when carrying out the alpha scattering experiment, he observed that some alpha particles got deflected from their course. as alpha particles are helium nuclei, they are positively charged. the fact that they deviate made him think that there might be some repulsion between the particles and the nucleus. as positive charges repel each other, he determined the nucleus to be positively charged.
If Rutherford made bombarded aluminum foil with alpha particles instead of gold foil what observations would he have used?
The scattering angles would have changed, but the qualitative results would also change: the reason Rutherford chose gold was because it is EXTREMELY malleable. One can stretch gold foil until it is only a few atoms thick in places, which is not possible with aluminum. If the foil were too thick, there would be no transmission of particles at all; the whole point was to demonstrate that most alpha particles passed through unchanged, but some of them scattered, which is only possible with a VERY thin foil.
Why gold foil is used in Rutherford experiment?
In the experiment, Rutherford found the nucleus using gold foil.because he used a thin sheet of gold foil.Because he used a gold foil (the only metal that can be hammered into a 1 atom thick foil without tearing) in an attempt to scatter alpha particles.The unexpected result that instead of all of the alpha particles scattering through small forward angles, a few bounced almost directly back to the source. This made the Thompson "plum pudding" model of the atom unworkable and suggested that each atom had a tiny "infinitely hard" kernel somewhere inside it. Rutherford named this kernel the nucleus.

What was one of the most lasting result of the Curies' research?
On a purely foundational level, the Curies were the first to show that atoms were not unchangeable -- that radioactivity was not a chemical reaction but, instead, comes from the element itself. Radium, which the Curies discovered, is a highly radioactive source of alpha particles. It was used in Rutherford's experiment that showed the atom had a nuclear structure. For many decades, radium was also used as a means to kill tumors.

How did the Rutherford experiment prove the existence of the nucleus?
The Gold Foil experiment demonstrated the (at the time) surprising result that atoms had nuclei. The prevaling model for atoms at the time has been described as "grapes in Jell-O" (with electrons - "grapes" - suspended in a uniform field of positive charge, the "Jell-O"), and the alpha particles Rutherford (actually, it was his students, Hans Geiger and Ernest Marsden) was shooting at the foil were expected to pass nearly straight through with only minor deviations. Instead, what was observed was what Rutherford described as "firing a 15-inch shell at a piece of tissue paper and having it come back and hit you," because it turns out that all the positive charge in the atom is concentrated within a very small region ... the nucleus, and the alpha particles recoiled quite strongly from this concentration of charge.
What actions will a narcissist take if they expected to be asked a straight question by someone but the question was a guarded one instead?
They will lie. They will say what ever is best for THEM.
After 1911 most scientists accepted the theory that the nucleus of an atom was very dense and very small and has a positive charge. What led scientists to accept this theory?
The breakthrough was the alpha particle scattering experiments of Marsden, Geiger and Rutherford. Basically they fired a beam of alpha particles (which are small, positively charged particles emitted by some radioactive sources), at a thin metal foil. Unexpectedly, instead of the slight scattering of the beam they expected, they found a very few particles were scattered back towards the source. They could only explain this if the metal atoms had a tiny central nucleus with a positive charge to repel the alpha particles. If you search you should be able to find Rutherford's own account of those experiments.
What important discovery did Ernest Rutherford make?
He found that the atom was made up of mostly empty space.
What is the Contribution of ernest Rutherford to science?
Ernest Rutherford contributed to the understanding of the atom. He used J.J Thomsons model and conducted a expirements in which he shot positively charged particles throught a thin gold foil. He predicted that all the high speed particles would pass straight through the foil without being affected by the gold atoms. Instead, the results showed that while most particles did behave as predicted, some were greatly deflected.
What Rutherford discover in his gold foil experiment?
He found that the atom was made up of mostly empty space.
What will happen if the beta particles would be there in the scattering experiment instead of alpha particles?
then you would get a girlfriend instead of asking questions on wikianswers

What can you use instead of You will?
Instead of "You will," you can use phrases like "You are likely to," "You may," or "It is expected that."

Why did the outcome of the 1948 presidential election shock most U.S. citizens?
Most of the nation expected Dewey to win instead of Truman.
